Embedded systems and M2M (machine to machine) communications are a daily occurrence. If you have ever been to a public parking lot, gotten a ticket to enter, and upon return, inserted that ticket into a payment kiosk, swiped your credit or debit card for payment, and finally insert the authorized ticket into the exit kiosk, you have encountered an M2M system.

Security of our credit cards, ATM cards, and pre-loaded ISO-7816 smart cards is a vital component of every POS (point of sale) system. This is especially true when they are communicating by wireless.

Cypherbridge Systems of Carlsbad, California software stacks are targeted at small-to-medium memory applications, where space, power and performance are carefully balanced. The basic software solution is built around the uSSL public-key infrastructure security and encryption stacks.

Cypherbridge showed BSN* a working demo system with credit card transaction processing built around the Wyless Group secure wireless data network for M2M communications.

Cypherbridge’s uSSL protocol includes self-test support for integration, test, and compatibility verification. uSSL includes a network adaptation layer to integrate with a variety of wired and wireless networks. The industry proven uSSL embedded security library and SDK provides the low-footprint MCU based security foundation, implementing SSL/TLS encryption and hash algorithms to connect with cloud-based transaction servers.

Cypherbridge AK200 POS Terminal application has a Payment Clearing House module. In partnership with a leading payment clearing house, the POS client application is pre-tested with transaction servers. The uSSL security layer and client application work in tandem to securely process authorizations and transactions. A range of transaction models can be used including standard swipe, P2PE (Point to Point Encryption), or hosted payments depending on the business model.

We are sure to see more and more emphasis placed on secure wireless cashless transactions similar to what Cypherbridge has developed.
